The class is fully encapsulated

The ownerName variable breaks encapsulation

The cardlD and limit variables break polymorphism

The setCardlnformation method breaks encapsulation

An exception is thrown at runtime.

Yen and Euro both return correct values

Compilation fails because of an error at line 25.

The time to determine whether a Person object is contained in a HashSet is constant and does NOT depend on the size of the map

Deleting a Person key from a HashMap will delete all map entries for all keys of type Person

Inserting a second Person object into a HashSet will cause the first Person object to be removed as a duplicate.

The time to find the value from HashMap with a Person key depends on the size of the map.

The code compiles and the output is 2

If lines 16, 17 and 18 were removed, the code would compile and

If lines 24, 25 and 26 were removed, the code would compile and the output would be 1

D. If lines 24, 25 and 26 were removed, compilation would fail
